The Cybergun Colt M4A1 carbine strikes a perfect balance between looks and functionality and delivers semi/full automatic firepower at shot velocities needed to advance your squad toward victory. This gun has a metal barrel with a weight relieved ABS plastic stock & receiver. The gun weighs slightly under 5 lbs and is comfortable to carry in the battlefield for extended airsoft skirmishes. The Colt M4A1 carbine features a detachable carry handle that exposes Weaver/Picatinny rail for mounting optional shooting accessories, a high capacity 300 rd magazine and a shot velocity of 335-345 fps (using .20g BBs). The gun has sling mounts that allow a gun sling to be attached for easy carrying, and the adjustable hop-up unit can be tweaked for the long range accuracy needed to dispatch faraway battlefield targets.

Things I liked: The look and feel of this gun is very close to real. A holographic scope attached to the top rail, and once dialed in, it was very accurate. Lots of family fun in the basement with a homemade shooting range.

Things I would have changed: The magazine will lose prime quick if the rifle is fired too much in automatic. Everyone fights over who gets to use it.

What others should know: I got this for my son for x-mas and it started having problems almost immediately. The mounting for the butt-stock started coming loose the first time he used it and got progressively worse. Next it started jamming - a lot - to the point where it is unusable. It is out of warranty (only 30 days) so it just sits. I recommend to pass on this one, save your money, and get a better model. That's what we will be doing - only starting from $0 rather than $130.
